Directions

Make the Peanut Butter Dough: In a bowl, beat together the peanut butter, butter, and brown sugar until light and fluffy. Beat in the egg and vanilla extract. In a separate bowl, whisk together the flour, baking soda, and salt. Gradually mix the dry ingredients into the wet ingredients until just combined.
Make the Brownie Dough: In another bowl, whisk together the melted butter and white sugar. Beat in the cocoa powder until smooth, then add the egg and vanilla extract. Fold in the flour, baking powder, salt, and chocolate chips until no dry streaks remain.
Chill the Doughs: Chill both doughs for 30 minutes in the refrigerator to make them easier to work with.
Scoop and Swirl: Scoop 1-2 tablespoon portions of each dough and place them side by side on a parchment-lined baking sheet. Use a toothpick or skewer to gently swirl the two doughs together in a marble pattern.
Bake: Bake at 350°F (175°C) for 9-11 minutes, or until the tops are lightly crackly and the edges are just set. The centers will still be quite soft, but they will firm up as they cool.
Cool and Serve: Allow the cookies to cool on the baking sheet for 5-10 minutes before transferring them to a wire rack to cool completely. Enjoy your delicious Peanut Butter Brownie Swirl Cookies!

Variations

Add Nuts: For an extra crunch, add chopped peanuts or walnuts to the peanut butter dough.

Storage/Reheating

Reheating: To enjoy warm cookies, microwave them for 10-15 seconds.

FAQs

1. Can I use crunchy peanut butter instead of creamy?

Yes, you can substitute crunchy peanut butter for creamy peanut butter. It will add a bit more texture to the cookies.

2. Can I use a different kind of chocolate for the brownie dough?

Definitely! You can use milk chocolate, dark chocolate, or even white chocolate chips for a unique twist.

3. Why do I need to chill the dough?

Chilling the dough makes it easier to handle and helps the cookies maintain their shape while baking, preventing them from spreading too much.

4. How do I get the perfect swirl in my cookies?

Scoop small amounts of both doughs and place them side by side on the baking sheet. Then, use a toothpick or skewer to gently swirl the doughs together. Don’t overdo it—just a few swirls will create a beautiful marble effect.

9. How can I make these cookies more peanut buttery?

For a more intense peanut butter flavor, try adding a bit more peanut butter to the dough or use peanut butter chips in addition to the chocolate chips.
